To all whom it may concern:

Be'it known that we, WALTER. W. Km-

PATRICK and EUGENE T. Boo'r'n, citizens of the United. States, residin at Atlanta, in the county of Fulton and tate of Georgia, have invented certain newand useful Improvements in Gasolene-Vending Machines, of which the following is a, descri' tion. This invention relates 'to' li ui vending machines and more particular y to an improved measuring mechanism for gasolene vendingmachines.

Ordinarily persons buying gasolene from pumping 51211310115 have no correct register of the amount of gasolene that flows through the pipes to the tank on .their automobile. The pumps are so arranged and adjusted that each time the piston of the pump is reversed by a crank, apredetermined of gasolene is said to be delivered to the asoilene tank on the automobile. There is, ow-

I ever, no way for the purchaser to know Whether he1s getting his correct measure,

"thus the purchaser will. for which he'is paying.

since the packing rings or leathers on the piston head in the pump supplying the gasoene due to its constant use may leak and when the'piston travels forward to force the gasolene through the supply pipes to the automobile tank, a certaln amount of gaso-J lene may leak by these packing rings and not get the amount The object of this invention is, therefore, to' rovideha measuring device attachable to t e ordinary-pumping mechanism of a gasolene supply station so that the purchaser may see how much gasolene he 1s getting and thereby insure that a correct and full measure is delivered to his asolene tank.

The above and other 0 jects and novel features of this invention will be apparent from the following description taken in connection with the drawing, which .forms a part of this specification.

The drawing illustrates a gasolene pumping mechanism equipped with a measuring mechanism embodying this invention.

Referring to the drawing, the base 10 sup orts a li uid or gasolene container 11 in e form 0 a c linder which is supplied with gasolene .in t e usual manner'from an underground tank 12 and pipe 13 indicatedin dotted lines. The piston head 14 works up and down in the cylinder 11 and has a extending upwar y; drefrom through the stem or rod 15. ri di'fi'connected to it and Specification of Letters Patent.

cover 16 of the cylinder. One face of the piston rod 15 is provided with a rack 17.

and a cpinion 18 on the crank shaft 19 is adapte to mesh with the. rack 17 and reciprocate the iston 14 when the crank shaft 19 is turned y the crank handle 20 on the i I outside of the casing 21 which incloses the aforementioned parts.

On its up stroke the piston head 14 is designed to force asolene from the container 11 through a pipe 22 into the receiver R.

mounted on a standard 23v carried by the upper end of the casing 21. The pipe 22 is attached to the head or upper end 16 of the cylinder 11 and near its attached end it has a check valve 24 which prevents the return of the liquid forced into the'pipe 22 by the piston 14. I

The receiver R consists of upper and lower metal ends 25 and 26 which hold'in place between them a glass cylinder 27. The

glass cylinder 27 is transparent and is marked'in gallons as indicated, so that the purchaser may see at a glancehow much gasolene i's'being delivered to his tank. The

receiver R shown in the drawing is arranged 1 to hold a little more than five allons of gasolene so that the purchaser willbe able to see that he is etting exactly the amount he has paid for. %t will be understood that a glass tube marked as indicated and attached to. a metal receiver may also be used to indicate the amount of gasolene in the receiver} .90 rest in suitably packed grooves in the opposed faces of the upper and lower The upper'and lower ends of the glass cylinder 2 plates 25 and 26, and the lates are clamped tightly to the ends of t ecylinder 27 by means of rods 28 which extend between the plates 25, 26 and are secured by nuts 29 threaded on the ends of the rods 28.

The upper plate 25 has an opening 30 in itwhich 00I1t1t11t6$ the inlet of the receiver R and to which the upper end of the pipe 22 is connected. The lower plate 26 has an openin 31 therein which constitutes the outlet of t e receiver R. The outer end of the 0 ening 31 is. provided with a nipple to w ich a pipe or hose 32 may-be attached,

' which pipe or hose constitutes the conduit for lea ng the gasolene to an automobile gasolene tank.-

The inner end of the opening'3'1 is bev I 'eled' so asto form a seat 33 for the valve 34 which controlsthe flowo'f liquid from the receiver B te the conduit 32 The valve 34 lot i is carried-by 'a rod 35 which extends upwardly through the receiver R and out through an opening in the top plate 25. The

valve rod is'connected to one end of a lever 36 which is mounted between its ends on a fulcrum 37. The opposite end of the lever 36 is connected to an operating rod 38 which extends downwardly through packed openings in the top and bottom plates 25 and 26 and also extends through a guide 39 within the casing 21. The lower end of the operating rod 38 is bent outwardly as at 40 and then horizontally as at 41. The horizontal portion 41 of the operating rod is pivoted intermediate its ends at 42- leaving a free s end 43, by means of which the rod on the opposite side of the-fulcrum42 may be raised to close the valve 34 to its seat One end of a spring 44 is attached at 45 to the operating rod 38 and the other end 46 of the spring is free to move independently of the rod. The spring'44 is V-shaped and its apex 47 extends upwardly away from the rod 38 and is located in the path of a lug 48 on the side of the piston rod 15. In the positi-onshown in the drawing, the piston head. 14 and its.

rod 15 are be nning the down stroke and thelug .48 is t erefore pressing against the before it presses past the spring. The downward pull exerted by the lug '48 opens the"' drawin v4 deliver iquid to the gasolene tank or other spring 44 which is slightly bent at its apex so that the lug 48 will exert a downward pull valve 34 and permits the liquid to flow out of the receiver R into the conduit 32 and the gasolene tank or other receptacle into which the hose 32 discharges. Parts shown in the are. in the position in which they receptacle. After the lug 48 passes the spring 44 and just before the piston 14 completes its .down stroke, the lug 48 engages the I j end 43 of'the operating rod 38 and through the connections of the rod 38, lever 36 and the rod 35, the valve 34 is restored to its seat 33' to close the outlet of the receiver R. The

usual arrangement is such that the piston 14 1 is adjusted to deliver a certain exact quantityto the receiver R, but if the quantity is shown to be less by the markingson the receiver, the customer will, of course, not be charged for the full amount which the piston is supposed to deliver. The check valve 24 prevents the return of the gasolene .from

' the pipe 22 to the cylinder 11. Just before the plston reaches the limit of its upward movement, the lug 48 forces ass the apex 47 of the spring 44, but this oesnot operate the valve 34 since the thrust is in the upward direction and the valve is already seated. In

order to open the valve 34, the crank handle 20 must be reversed and this moves the lug 48 downwardly against the apex 47 of the spring 44 thrusting the operating rod 38 downwardly and lifting the valve 34 off its seat, thereby permitting the measured (plantity of gasolene to flow out of ,the receiver through the conduit 32 and into a tank or receptacle. As the breakage of the glass cylinder 27 would expose the apparatus and building containing it to fire,.'I surround this cylinder with a steel wire jacket 50 of any for delivering liquid therefrom, a rod connected to said piston and extending upwardly above the same. and having a lug thereon, means .for reciprocating said rod and the piston connected to it, a receiver supported above said container and piston, a pipe leading from said container to the upper end of said receiver, said receiver having a transparent portion marked so that the amount of liquidtherein may be observed and determined, said receiver also having an outlet in itslower end, a valve controlling said outlet, and mechanism for operating said valve comprising devices connected to said valve, one of said devices being engageable by the lug on the piston rod to open the valve at the upper end of its stroke and another of said devices being engage'able by said lug to close the valve at the lower end of its stroke.
